of an automobile for example,. showing disc or plate mounted thereon for receiving display matter. I

Figure 2 is a front elevation the hub of an automobile wheel showing in longitudinal section parts for attachment to the axle which carriesa disc or. plate shownfin Figure Figure 3 a f-ront elevation of a rear wheel-hub showing in longitudinal section parts also for carrying a disc or plate.

Figure 4 is a plan of part of a rear wheel together with a fender, shown in section, with which my device in one of its forms is associated.

The purpose of my invention, as in others of its type, is that such a mounting may be provided for a disc or plate that said disc or plate will retain a fixed position with respect to the wheel and hub while said wheel is in rotation and such also that both the front and rear wheels may be equipped.

in Figure l of the drawing, 1 designates a wheel and its tire, while 2 is a disc or plate of suitable material such as fiber, for example, mounted within the wheel-rim.

The means for mounting the disc at the front wheel is shown in Figure 2 wherein 3 is a part of the wheelhub threaded in the usual manner at 4: for receiving the-usual hub-cap. However, for the purpose of my invention said cap is removed from the hub exposing the axle 6 and its retaining nut 7 for the wheel. Preferably, there is screwed upon the projecting end of the axle outside the nut 7 an additional nut 8 corresponding with the said nut 7 both in form and position. A member 9 provided with an opening 10 extending longitudinally therethrough is fitted upon the said nuts, said opening corresponding in form to the latter so as to be non-rotatable thereon. Said member is extended toward the wheelhub and is cupped. as shown to enclose and cover the threaded portion 4 andterminates in a flange 11 whose outer face is parallel to the plane of the wheel, not shown in Figure 2, said flange having secured upon it the described disc or plan-22 as by bolts 12 for example. 7

In addition, .the member isreduced in diameter at its outer end where it encloses the nuts? and 8, being a mere preference, and is threaded to receivexthe huh-cap 5. However in order to retain the member 9 in position a hole 13 is boredflthrouggh it to register with the usual cotterpin hole 13 of the axle 6 and a pin id of a length to extend through the said member and axle is inserted and engages theycastellated' nut 7 preventing it from turning on th axle with said member 9, after which the cap 5 i'sfs'crewedto position.

It isathusseeii that since the whole-strucass described is, afiixe'clto the axle it is sta tionary while thewheel-hub isfr'ee to turn. The use of the nut, it may be stated, is merely to, in effect, extend the axle giving the member 9 a long staunch bearing thereon and providing, also, a greater threaded area for the said cap 5.

In Figures 3 and 4 a slightly different arrangement for a rear wheel is made use of and at which place the rear axle, of course, revolves. The hub-cap is denoted at 15 and preferably it is secured against movement relatively to the hub 16 by' any suitable means such as a lug or car 17, for example, which extends therefrom to overlie the hub, and a screw 18 extending through it into the hub secures the cap in position. At its outer end the cap has an extension or stud 2O axially in linewith the axis of rotation of the hub which provides a support for a cap 21. This cap as may be seen encloses the hub-cap 15 and at its inner end has a flange 22 corresponding to the flange 11 of Figure 1 and receives the said disc or plate 2, as in the first instance, bolts 28 being employed to secure the flange and disc relatively. The opposite or closed end of the cap 21 is provided with a bore at the axis thereof to take over the said stud in a free running manner, there being a retaining nut or washer 2 for holding the cap in place.

The bore of the cap 21 may be but slightly larger than the diameter of the hub-cap 15 and preferably the cavity between the two is filled with grease for lubricating purposes.

and there may be openings 25 in the walls of the last named cap through which grease may outwardly fiow.

None but a slight control of the cap 21 to prevent its rolling with the wheel is necessary and for this purpose there is used a light coil spring 26 connected at its ends to the periphery of the disc 2, Figure l, and to the fender '27. This arrangement extends horizontally from and holds the disc stationary and yet the natural vertical movement of the fender with respect to the wheel will have but little elfect in rocking said disc I am aware of the fact advertising display discs have been mounted on wheel hubs in such manner that the wheel may revolve without the revolution of the disc, one of the methods being to secure a Weight to the disc with the idea that the zone having such weight will act to overcome the friction at the point of support of the disc. This, however, has been found to be unsatisfactory since the disc cannot be prevented from swinging after the manner of a pendulum due to jolts and jars and changing speeds of travel on the road making the display matter difficult to read or to keep the eyeupon. In another form it was proposed to prevent the disc rotating or having swinging movement by connecting to it a rigid memher which member was to be attached to a part of the vehicle body. Now, since the body of the vehicle always has movement with respect to the wheel in a vertical direction it is not possible to make such attachmentby means of a rigid connecting menr ber.

In my device, however, I employ the coil spring 26 as described which holds the disc practically stationary and although the body of the vehicle may have movement relatively to the wheel vertically the spring conforms to the changing conditions.

An effective device for the wheels of a vehicle is provided that will stand up under long use. An advantage among others is that the parts may be easily and quickly installed or removed.
